Hope folks that go to the show give some feedback on the DIY DAC if they get to hear it in the system in 218.

This project was to show folks how to get started with a simple DAC project that will playback all PCM rates up to DXD with an asynchronous USB computer interface. My hope is it will inspire folks that think it is to hard to build electronics to give it a try.

Disclaimer is that you are working with AC line voltages so the first time it is a very good idea to ask someone to look it over and check for problems before plugging it in to AC power. That it is why the DCAudioDIY folks are a great group to help folks try things.

The ASUS Netbook was a refurbished unit that came with Windows 7 Starter for $129.00. I just did the free Windows 10 upgrade. The entire music server and DIY HiRez DAC was under $300.

Got the DIY DAC out and installed a TI(NS) LME49720 dual opamp to replace the AD827 that comes stock in the unit. That was a nice sonic upgrade.

Also have a NS LM4562 and two single Burson discrete opamps to try once I have built an adaptor to connect it to the PC Board. The area around the DAC chip socket is to small to fit the Bursons. These are the generation one back from the present Burson design, so will be interesting. They are supposed to be a direct replacement for the AD827's. Will probably add bypass caps to the extender board, since it now will add a few inches of wire. Want to keep stability with the new change.
